Please update your forum profile with the output of the following command (do not post the output in this thread):

Code:

zmcontrol -v

You've not really provided any evidence that the email came into your server nor exactly what you mean by 'bouncing', why would the mail be undelivered? You do realise that a bounce can take up to five days before the sender receives notification that there was a problem, don't you? Are the emails in your deferred queue? Have a look in the log files and see if the email has arrived at you server and what happened to it. You need to provide some examples of what exactly is happening on your server.

Thanks for the reply . The output is
Release 6.0.1_GA_1816.F11_20090911184139 F11 FOSS edition.

The exact problem is the undelivered mails is the deferred queue are not bounce back immediately to the sender. i need to change the bounce_queue_lifetime parameter , but unable to save the postfix settings. so the sender gets undelivered bounce mails much delayed.

Please put that in your forum profile as I asked in my previous post, it's no use here as we have to keep asking every time you post what version of Zimbra you're using.

I have changed the bounce_queue_lifetime parameter and restart the MTA. while restarting the MTA this error is coming like
/opt/zimbra/bin/zmshutil: line 39: export: `=1m': not a valid identifier
/opt/zimbra/bin/zmshutil: line 39: export: `=10s': not a valid identifier

Still the error persists while restarting the MTA Service
